Abstract

L'invention concerne une unité de compression externe orthopédique (100) ayant une unité de plaque de verrouillage et un procédé de verrouillage et de compression des os fracturés (102) sans contact ni frottement entre la plaque (103) et l'os (102), l'unité de plaque de verrouillage (101) comprenant une plaque de verrouillage (103), un appareil externe (104) et un support (105), la plaque de verrouillage (103) comprenant une pluralité de trous de verrouillage (106) et au moins un trou allongé (107), le support (105) étant placé sur le trou allongé (107). Le support (105) est configuré pour maintenir la plaque de verrouillage (103) au-dessus de l'os (102) pour permettre la réalisation d'un déplacement requis de la plaque de verrouillage (103) dans une direction horizontale. Par conséquent, la fixation de l'unité de compression (401) à l'aide d'une vis non de verrouillage (411) sur la plaque (103) convertit le déplacement vertical d'une vis à tête en un déplacement horizontal d'une tige de raccordement (408) de l'unité de compression (401), permettant ainsi de déplacer la plaque (103) avec une extrémité de l'os fracturé (102) vers le site fracturé (110) en produisant ainsi une compression entre les os fracturés (102).
